Ultimately apple will sell developer devices at the price point of their Mac pro devices that come with all the approved tech you are allowed to use to build end user services/apps. In addition to the high purchase price you will have to sign up for a developer account and pay annually.

Everyone else will buy consumer oriented devices that are as open as the ipad.

It's not a bicycle for the mind its a train and if you dress appropriately and pay your fee you may set up a concession stand on the route.
